Many years ago I used an App called DVD Master Pro for the Mac. That App has long gone and been replaced by another called MacX DVD Ripper Pro for around $30 US. This App does pretty much everything one would expect from a fully fledged DVD Ripping suite If you just want audio MP3 form your discs then that’s fine. If you want a full ISO image of your DVD - encrypted DVD’S are handled - then select the “Backup” profile and make the necessary adjustments to backup the DVD to an ISO image which can then be used with VLC to converter to different formats, write to a disc and so on. MacX DVD Ripper Pro is extremely accessible though first time users may find the App a little daunting given the scope of features and functionality available. Thankfully the web site provides plenty of documentation so it might be a good idea to read the “Quick Start” tutorials and examine the layout of the main screens before you attempt any serious projects.
